Maybe it's something in the water, but somehow New Yorkers are living longer than the rest of the United States.

Mayor Michael Bloomberg unveiled new data Tuesday on the city's health. The data show that Big Apple babies born from 2010 on will live an average of two years longer than their national counterparts, the mayor said.

The mayor touted his health initiatives during his tenure, including the ban on outdoor smoking, as the leading factor for this trend.

"Our willingness to invest in health care and bold interventions is paying off in improved health outcomes, decreased infant mortality and increased life expectancy," Bloomberg said in a statement.

The average life expectancy at birth in the city is 80.9 years while the national average is 78.7. The age has increased by three years since 2001 in New York, according to the study by the city's Department of Health.

The mayor also noted that the infant mortality rate was 4.7 deaths per 1,000 live births last year. That was a 23 percent decrease from 2001, when the rate was about six deaths per 1,000 live births, which is the national average.

"Improvements in medical care, increased outreach to communities and innovative ideas are making the difference and saving lives," Deputy Mayor Linda Gibbs said in a statement.
